MOTOR.

SEECFCATION forming part of Letters Patent No. 323,943, dated August 11,1885. Application filed June 26, 1895. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW MARCH, of Lexington, Lafayette county,Missouri,have invented certain new and useful Improvements in MechanicalMotors, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to certain improvero ments in .light motors adaptedfor actuating 2o Fig. 2 is a side elevation ofthe same.

fans, sewing-machines, Snc., the object being to provide a noiseless,compact, and efficient motor of this class.

The invention consists more particularly of a novel combination andarrangement ofwinding mechanism with the other parts, substantially ashereinafter set forth.

ln the drawings, Figure 1 is a front elevation of a motor embodying myimprovements. Fig. 3 is a view of the inner side of the main gearwheel,having a portion of the noiseless ratchet mechanism affixed thereto.Fig. 4 is a longitudinal section through the ratchet mechanism and aportion of the winding-drum. Fig. 5 is an enlarged view of a portion ofthe winding-drum journal and the crank which engages the same; and Fig.6 is a perspective view of a flexible disk employed in making 3o up theratchet mechanism.

rllhe letter A indicates a pair of vertical plates, in which are formedbearings for the various shafts. A rod, A, is located between the upperends of these plates, and is removably held in position by a screw, A2,passing th rough the plates into the end of the rod. The lower ends ofthe plates A are bent outward at a right angle to form feet, wherebythey are securely affixed to a base-plate, S", and to any 4o desirablesupport.

I prefer to inelose the motor in a dust-proof box, so that it may beprotected from injury that it might otherwise receive, and in such caselthe letter S would represent the bottom 5 of the box.

winding-drum, g, and a ratchet-wheel h. The

said drum is provided at each end with a disk,

gl, and the ratchet-wheel h may be either attached to one of these disksor it may be formed integral therewith, as desired. i

Mounted loosely upon the end g3 ofthe main shaft, and between theratchet-wheel and the framing, is the main gear-wheel F, having a pawl,h, pivoted at hl to one of its spokes. u The ratchetwheel h is formedwith a recess, g, upon its outer face, and a washer, g, made of springmetal, is located in the recess. The washer gLL is bent in one directionacross its diameter, so that when the mainvgear F is pressed against itsconvex side its periphery will press upon the bottom of the recess 96,as shown.

A pin, h5, projects outward from near the periphery of the washer g4,and an arm, h3, forming a part of the pawl h, has an oblique slot, h4,running a portion of its length,which is engaged by the said pin.

The operation of the ratchet mechanism when thus constructed will be asfollows: Upon turning the main shaft toward the left hand in Fig. 8, thefriction of the washer g4 against the bottom of the recess in theratchetwheel h willbe sufficient to cause the washer to revolvetherewith, and the pin h5, acting upon the slotted arm of the pawl h,raises the saine and holds it clear of the ratchet-wheel teeth untilthedirection of movement is reversed. The pin in this latter case causesthe pawl to engage the teeth, and the main gearwheel will be rotatedwith the drum. The opening g5 through the washer should be somewhatlarger than the diameter of the main shaft, so that after the pawl hasbeen lifted the washer will remain stationary with the main gear untilmovement of the drumshall be reversed. Y

The end i2 of the main shaft i is circular in cross-section, andprojects sufficiently far to allow movement of a crank, N, which is tobe used in winding the rope g upon the drum, and therebyraising theweight g2. The letter a2 represents the handle of the crank N. The crankis removable from the main shaft, and the inner end of its body a isformed with a socket, i, and with a spiral surface, i5, for en gaging apin, i', inserted transversely of the Vmain shaft.

When the crank is in place upon the main IOO shaft, as shown in Fig. l,it is obvious that by turning it in one direction the concave shoulderi, formed at the base of the spiral surface i, will engage the pin t"upon said shaft, and the weight gl' will be wound up; also, that byturning the crank in an opposite direction the spiral surface 5 willsimply glide over thepin without turning` the shaft, thereby preventingany accidental strain heilig' thrown upon the ratchet mech an ism Fromthe main gear F power is communicated to the shaft e, carrying pinion eand gear E, thence to the shaft d, carrying` pinion d and gear D, thenceto the crank-shaft c, having the crank c2 at about the center of itslength, and carrying the pinion cand the gea-r (l, and thence to shaftI), carrying pinion b', beltpulley b2, and iiy-whcel B.

The crank ci may be connected to any style of light lnaehinereq uiringan oscillating' Inovement by means of a connecting-rod, as cic, and thepulley b2 can be used to connect the motor to such machines as requirerotary motion.

The letter represents an opening' in the support S for the passage ofthe weight g2.

Having thus described my invention7 what I claim isw l, In combinationwith the winding 1nechanisin and the intermediate motive traincrank-shaft c, having crank c located at about the center of its length.and carrying pinion c and gear C, shaft located above the entire train,and carrying` fiywheel B, belt-pulley Il, and pinion b', substantiallyas described. and for the purposes herein set forth.

ln a motor, the combination ofthe drum g, rigidly connected to the mainshaft, a ratchet-wheel, lef', revolving with said drum7 and providedwith a recess, g, upon its outer face, washer ,f/Qlocated in said recessand fitted with a pin, h5, main gear F, having` a pawl, l, pivotedthereto7 and an arm which projects from said pawl and is engaged by saidpin, substantially as described.

3. The combination, with the main shaft provided with atransversely-proiecting pin7 f/, ol' the crank N, formed with a socket,and with a spiral surface and a shoulder, substantially as described.

In testimony whereoillatiix my signature in presence of two witnesses.
